Histone deacetylases are promising molecular targets for the development of antitumor agents. A novel series of histone deacetylase inhibitors of the hydroxamic acid type were synthesized for structure-activity studies. Thirteen tricyclic dibenzo-diazepine, -oxazepine, and -thiazepine analogues were studied and shown to induce variable degrees of histone H3/H4 and tubulin acetylation in a cellular
组蛋白脱乙酰基酶是开发抗肿瘤剂的有希望的分子靶标。合成了一系列新的异羟肟酸类型的组蛋白脱乙酰基酶抑制剂用于结构活性研究。研究了十三种三环二苯并二氮杂卓,-奥氮平和-硫氮平类似物,并显示在对全反式视黄酸(ATRA)敏感的骨髓性白血病细胞模型中,可诱导不同程度的组蛋白H3 / H4和微管蛋白乙酰化。进行了三种底物的乙酰化,肿瘤细胞生长抑制和ATRA依赖性细胞分化之间的多参数关联,提供了控制这些活性的化学功能的信息。对于两种类似物,证明了在动物中的抗肿瘤活性。
